What is ASTM A276 TP316 material?

What is the meaning of ASTM A276?

The ASTM A276 standard covers hot-worked or cold-worked stainless steel bars (excluding bars intended for reforging). The specification covers various shapes, such as round, square, and hexagonal, as well as hot-rolled or extruded shapes such as angles, T-bars, and channels. The specification covers commonly used stainless steel types, as well as free-machining steel grades for general corrosion resistance and high-temperature applications.
